Sedum praealtum

It features sub-woody brown or grayish stems and fleshy, hairless leaves. It grows to 3 feet tall (90cm) and spreads to 4 feet (1.2m). The lime-green leaves are spatulated and are 1.5 inches (3.8cm) long, arranged in rosettes. Large clusters of bright, star-like yellow flowers appear from late winter to spring. The plant tends to be summer-dormant. It is closely related to Sedum dendroideum and would look similar to it, but 'dendroideum' can be differentiated by the existence of a line of subepidermal glands on its margins near the leaf tips. ==Cultivation==

It can be used as a bonsai due to its treelike appearance and it bears a resemblance to the Jade plant. It easily grows in rock gardens in well-drained, poor soils. Propagation can easily be done by cuttings and the plant is not cold hardy. ==Uses==

A spermicide developed from this plant, that helps women control birth rates without any major side effects, was around 20% more effective than nonoxynol-9. Its leaf substance has been traditionally used for burns, hemorrhoids and dysentery, gum inflammation, and as well as an eye drop for conjunctivitis and irritations. ==References==
